Polystyrene particles, Paramagnetic and Streptavidin-modified (PS-MAG-SA)
Our monodisperse Streptavidin-functionalized magnetic polystyrene particles are prepared via the following steps: i) preparation of monodisperse polystyrene particles using free-radical copolymerization of styrene and divinylbenzene ii) in situ coprecipitation of iron oxide nanoparticles within the polymer network iii) microencapsulation/Streptavidin modification. Through this strategy, Streptavidin-modified magnetic polystyrene particles with high monodispersity (CV < 5 %), high saturation magnetization, and high binding capacity for biotinylated ligands can be achieved. All magnetic polystyrene particles are available in a range of discrete sizes from 300 nm to 10 µm as a 1 % w/v aqueous suspension. They can be used in a variety of applications like cell separation, nucleic acid isolation, biomolecule purification, and particle-based immunoassays.
